I feel like I have the same issues with games at our house. I asked my sons' doc about game addiction and he says "addiction is when it interferes with daily life to the point where other areas are neglected". I've used timers, used them as priviledges, blocked out certain days of the week.... and games seemed to preoccupy my boys' thoughts where they are trying to justify or bargain their way to use it.

My opportunity came last month when our ol' tele finally broke laugh. Because I don't see television as a necessity I took my time replacing it.... about a month. The first two weeks was torturous for them and then.... they finally coped without it. Soon they picked up books and learned other ways to entertain themselves. I also didn't get the constant bargaining and petty arguments about games. We have a new tele now, and I've just put away the systems until summer.
